LUBRICATOR.

Specification of Letters Patent.

Patented Oct. 12, 1920.

Application filed March 15, 1920. Serial No. 365,989.

To all whom it may concern:

Be it known that I, ALLEN A. VAN Ons- DALE, a citizen of the United States residing at Philadelphia, in the county of lhiladelphia and State of Pennsylvania, have invented new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to lubricators and it has more particular reference to that type which may be conveniently designated as a splash feed lubricator, that is to say to lubricators dependent functionally upon the vibrations of the machine or engine to which it is attached for feeding the lubricant to the desired part or parts.

The main object of this invention is to provide a lubricator of the type referred to which is devoid of any vibratorily actuated valve.

Another object is to provide a splash feed lubricator with which is combined a renewable or removable container for the lubricant, said container before insertion in the lubricator being hermetically se'aled and when placed in position automatically punctured or unsealed, to feed the contained lubricant.

. A further object of this invention is to provide a lubricator of the type specified which includes a minimum of simple and easily constructed parts that can be readily assembled or dissociated.

'With the foregoing and other objects in view as will be more apparent as this description proceeds my invention consists essentially in the novel features of construe-- improvements. 1

Fig. 2is a transverse section taken substantially on the line 2-2 in the preceding figure.

Fig. 3-is a similar transverse section taken substantially I on the line 33 in Fi 1. %ig. 4is a detail view of the concavoconvex insert hereinafter more particularly described; and

Fig. 5is a perspective view-partly broken-of the lubricant container proper.

Referring to the drawings the numeral 10, desi ates the main or body portion of the lubrlcator which is provided with a cap or cover 11 appropriately threaded therein, a packing ring 12 being provided for the insuring of an air-closed joint. The lower end of the body portion 10, is screw-threaded at 13 to receive a similarly threaded supplemental or lower body portion 14 of approved cross section-hexagonal for exampleand which is formed with the customary axial extension 15 and threaded.nipple 16 by means of which the device can be readily connected in position or removed as desired. It is to be noted that the main and lower body portions 10, 14, when screwed together have a perfectly smooth joint 17 and that the former is provided with a lateral flange 18 which substantially divides the lubricator into upper and lower chambers 19, 20 respectively.

Formed internally of the lower chambers 20, are diametrically opposed lugs .or projections 21 in the notched out parts 22 whereof there isforced and seated a concave-convex or dished diaphragm 23 which when in place provides a series of openings 24 between its peripheral edge and the inner wall of the chamber 20 intervening the lugs or projections 21, for the purpose hereinafter explained. Axially central of the lateral flange 18 there is formed or threaded thereinto an open-ended cylindrical extension 25 the lower peripheral edge whereof may be serrated if desired, and projecting central thereabov is a conical projection 26 apertured at '27, with a series of openings for the passage therethrough of the lubricant as hereinafter set forth. 4 I

. The lubricant is preferably contained in an air and moisture proof container 28 which may be made of lead foil, paraffinpaper or thin sheet metal, and it is of dimension to fit easily on the upper chamber 19, and it will be readily understood that when the cap or cover 11 is screwed down into place the conical projection 26 will pierce the lower end 29 of said container 28 and cause the lubricant to ooze or discharge through the apertures 27 and cylindrical extension 25, into the dished diaphragm 23 until it rises to the level shown at 30 where it will seal any further outflow of said lubricant. Now assuming that the part of the machine or engine on which the lubricator is installed is subject to intermittent or constant vibration it will be readily seen that such vibrations will cause the lubricant contained in the dished diaphragm to be washed or splashed over the edges thereof through the apertures 27 whence it will travel down the inner wall of the lower body portion 14 to the outlet 31 and part or parts to be lubricated. Furthermore it will be understood that according to the frequency of vibration there will be a correspondingly increased or decreased feed of the lubricant, and that by providing an air vent 32 there will be a prompt replacement of the air which will be caused to bubble up throu h or past the extension 25 and apertures 2 surface 33 of the lubricant in the container 28. From the foregoing it will be readily seen that the action just described will take place and continue so long as the requisite degree of vibration is set u to cause a splash or wash-over of the lu ricant from the dished diaphragm 23, whereby an automatic feed of lubricant will take place to the part or parts to be lubricated. Furthermore when the container 28 becomes emptied it can be easily removed and replaced by a fresh one by simply removing the cap or cover 10 and picking it out with an appropriate tool or the fingers and to aid this removal opposed notches 34 may be provided in the upper" peripheral edge of t e main or body portion 10. While I have described and shown one practical and preferred embodiment of my invention I wish it'clearly understood that I do not limit m self to the precise details of construction disclosed as various changes in the shape and arrangement of the several parts can be effected without departing from the spirit and scope thereof; for example the lower body portion may be elbowed or angled to accommodate application of the lubricator in awkward and normally inaccessible positions, and it is intended to hereby include all such reasonable modifications as may fairly be construed as falling within the scope and ambit of the ap ended claims.

aving described my invention what I- claim as new and desire to secure by Letters Patent is a y 1. A splash feed lubricator comprising a till it rises to the upper portion, a

reservoir for the lubricant and having an outlet therefrom, a supplemental chamber disposed below the-reservoir for the lubricant a dished diaphragm seated in the supplemen tal chamber and having peripheral apertures for the passage of the lubricant therethrough when the lubricator is vibrated.

2. A splash feed lubricator comprising a reservoir having an outlet therefrom, a lubricant container adapted to seat in the reservoir, a supplemental chamber disposed below the reservoir, a dished diaphragm seated in the supplemental chamber and having peripheral openings for the passage of the lubricant therethrough when the lubricator is vibrated.

3. A splash feed lubricator comprising an upper portion having an outlet therefrom, a lubricant container adapted to seat in the upper portion an air tight cap for threaded engagement on the upper portion, a supplemental chamber threaded on the lower end of the upper portion, a dished diaphragm seated in the supplemental chamber and having peripheral openings for the passage of the lubricant therethrough when the lubricator is vibrated.

4. A splash feed lubricator comprising an upper portion having a threaded outlet therefrom, a lubricant container adapted to seat in the upper portion, a cylindrical extension threaded into the aforesaid outlet and having an'apertured conical projecting upper end extending into the upper portion, an air tight cap for threaded engagement on the upper portion, a supplemental chamber threaded on the lower end of the upper dished diaphragm seated in the supplemental chamber and having peripheral openings for the passage of the lubricant therethrough when the lubricator is vibrated.

5. A splash feed lubricator comprising an upper portion having an internally threaded outlet therefrom, a lubricant container adapted to seat in the upper portion, a cylindrical extension threaded into the afore; said outlet and having an apertured conical projecting upper end adapted to puncture the lower end of the lhbricant container, an airtight cap for threaded engage- I ment on the upper portion, a supplemental chamber threaded on the lower end of the upper portion, a dished diaphragm seated in the supplemental chamber and having for the passage of the peripheral openings when the lubricator lindrical extension threaded into the aforesaid outlet and having an apertured conical a lubricant container the inwardly projecting notched lugs of the supplemental chamber and thereby forming peripheral openings for the passage of the 10 lubricant when the lubricator is vibrated.

In testimony whereof I aflix my signature.
